Figs. 16a, 16D, 16C and 16d represent different plugging connections for the machine whereby punching and typing duplicating operations may be selectively carried out at different column positions of the card punch.

The typewriter The typewriter for controlling the card punch is preferably constructed as shown in Patents Nos. 1,777,055 and 1,873,512 which is now on the market and known commercially as the Electromatic, which is a product of the International Business Machines Corporation.

Fig. 3 shows the keyboard of which keys I0 are the alphabetic keys and other functional keys are shown, such as CR for carriage return, TAB, the tabulating key SP, space bar, special type or punctuation keys for punching a period asterisk (i), apostrophe diagonal number sign (ai), and aV comma these being principally used in connection with the present invention.

Briefly, referring to Fig. 2 a depression of the typing keys releases a latch II from a cam I2, permitting a spring-pressed lever I3 to move the cam I2 against the periphery of a continually rotating motor driven roller I4. The cam-I2 is rotated by contact with the roller I4, causing the carrier I5 of the cam to rock in a direction for l depressing a link I6 which, through linkage II, propels type bar I8 carried by the basket I9 ltowards the platen 2li to effect typing from the type denoted by the operated key. During the final increment of the moving Aof the type bar I8 it strikes a universal bar 22 to actuate the escapement lever 23 for releasing the escapement mechanism to eiect a carriage spacing movement. is effected for the bar SP similarly results in the downward movement of link I6' to operate a linkage 2B for actuating the escapement lever 23 to effect a carriage or letter spacing movement.

The carriage return mechanism operated by key CR (Fig. 3) is of the type disclosed in Patent No. 1,955,614. As is usual, the carriage return movement is accompanied by a line spacing operation.

The tabulating mechanism operated by the key TAB is such as shown in Patent No. 1,935,436 and includes the usual settable tabular stops 25.

For actuation of the keys there are solenoids 30, one for the various keys to be operated under control of another keyboard or instrumentalities. In the present case the disclosure of the typewriter solenoids the digit keys 0-9 inclusive and also for operating the above designated punctuation keys and the space bar. In general, energization of the solenoid 30 results in automatic operation of a key and the mechanism operated by the key whether it is a functional operation in the typewriter or a typing operation from selected type. In the wiring diagram to be described later there is shown the series of solenoids 30 and the designation affixed to each solenoid designates the particular key which is operated upon its energization.

Also mounted on the slotted rack 3I (Fig. 3a) which is carried by the carriage of the typewriter are marginal tabulator stops 32 which are xed at desired positions on the rack corresponding to positions in which certain functions should take place when the carriage reaches such column positions.

The stops 32 are of different shapes and the five used in the present machine have projections 32a, 3217, 32e, 32d and 32e at different heights as is evident in Fig. 3b. These projections contact and operate levers 33 at certain column positions of the carriage. For the three TAB stops 32 utilized in the present wiring diagram there are related contacts 34, 35, and 36 which are closed by the related lever 33.

The typewriter T (Fig. l) is shown mounted on a table 39 and adjacent the typewriter is an auxiliary keyboard K, the digit keys of which are operated to type on a sheet in the typewriter and to punch at the same time a card by'means of a distantly or nearby located punch P.

Card punching machine The `card punching machine used .in .connec- -tionwith the present .invention is of the type shown in 4the patent tn Frged Lee and AGeorge F. Daly, No. 1,976,618, .dated Qctober 9. 41934: .and .only so much of the operation thereof will be lexplainedaslis necessary foranundrerstanding of itsoperationin `c.onnectidn with `the present invention.

In general, the `punching machine contains a feed magazine53fromwhich, cards are.f,ed singly .frQm :the bottom of `the Amagazine as `is well .known by a picker `which feeds `the cards to a position under punches 5,5 andin lthe present machine the Vcarriage is preferably returned to co1- Auninl ofthe card to the punch es, preparatory to receiving the perforations effected b y the rst .manual punching operation. From this position the card is engaged at its Vrearedge b y a pusher 54.rnounted upon an escapement rack 56 which, .for each .operation of the Apunches permits the adyance of the card step `by step. A series of ,magnets 45 is adapted to -select the punches 55 for actuation in the following manner: Associated-.with each magnet 45 is a .pivoted armature 5.7 whosefreeendis connected Vto a `rod 58 which, through a bell crank 59, moves an interposer bar 6D to jthe left in Fig. 4 where it cooperates with a punch bar or plate 6| The forward movement of gthe interposer bar 60 is adapted to rock a `bail 62 pivoted `on a rod 63 and which bail is con- -nected to a spring pressed `depending link 64 whose lower free end is adapted to engage and .close thepunch magnet contacts 65. This, as will be described `in connection with the diagram, `closes a circuit through a punch magnet 66 which then attracts its armaturel and through-a link and bell crank connection 52 will draw downwardly on the pivoted punch `bar or plate 6| to force the selector interposer against the associated punch, thus perforating thelcard. `When the armature ,671s attracted by punch magnet 66 a projection on thehorizontal'link 5i!` closes contactsc, which contacts are also shown in Fig. 7 of the wiring diagram. Such contacts are closed .after perforating the card and before the punch carriage spaces to the next column position.

.Escapcmcnt mechanism The `escapement mechanism l'-.issh'own `herein in some detail in Figs. 13` and14butis fully shown and described in Patents No. .1,976,618-1andiNo. 1,426,223. It will suiiicefto saythatLwhen aninterposer 166 is depressed it `will rock a bail flr'attached to a shaft A"il and thefrockingv ofithisnshaft `will actuate the escapementlmechanismto space the card carriage a single column. Associated `with the escapement mechanism are contacts |28a and |282) (see Figs. 7, A13 and 111). These contacts correspond to similarly designatedfcontacts |23 in Patent No. 1,976,618. These contacts are normally closed but are openedbylthe escapement mechanism during the time that ftheacard carriage is spacing to `the lnextcolumn position y(see Fig. 13). When this `column position iha-s been reached, both of the contacts |28a1and |1281) (See Fig. 14.) Contacts |28u-are inseries with the duplicator circuit to prevent .arcingiat the master card analyzing brushes. :Contacts `126i) Vare utilized in other lcircuits to be lsubsequently described in connection with the wiring diagram.

Column selector The column selector for the machine illustrated herein is also well known and is shown in `the patent to George F. Daly et al., No. 2,016,706, dated October 3, 1935. As shown in Fig. 4 `as well as Fig. 7, it consists of a movable contactbrush 72 carried by the punch carriage engageablewth a reading strip comprising a common contact'strip 73 and contact points 14, some of which .are con-4 nected by plug connections so as to cause certain. functions to be performed when the carriage `is .at certain column positions in a manner to be su`b sequently explained. The contact Apoints 714 ,are individually connected to` plug sockets 'i5 of a`p1ugboard shown in Fig. 7 and the plug sockets are serially numbered 1-80, corresponding Ato the column positions of the card carriage.

Master card sensing .mechanism The machine shown herein is provided with a master card sensing mechanism so that 4certain data on themaster card'may be duplicated on the `blank card coordinated with the `99 and |ll| respectively, which arms are extended from the escapement rack 56.

The card M is manually placed in position and `travels back and forth with the card carriage.

vThe operation is such that the card is advanced step byA step past a set of brushesllll'as` each'of the columns of the card C pass their punching position. Brushes are provided for sensingthe digit positions -9 and also the index point positions l1 and 12. The 11 and 12 index point positions of the card are punched but, of course, there is no printing of such indications by the typewriter.

The brushes ||i| are mounted on an insulating block |2a and are moved vertically into contact with the card through linkage generally designated |33 which is controlled by the brush magn'etlll. The cooperating contact roller |05 is supported in the gate or door |06 which is pivoted at |01 and which, when the master card has been placed in position, is rocked downwardly into closed position where it is held by a spring-pressed latch |08. The free end of the gate is provided with a plunger which effects closure of the socalled door contacts H39 (see Fig. 7)

Also associated With the energizing circuit of the brush magnet are the so-called cutout contacts IIb` shown in the wiring diagram of Fig. 7. The means for operating these contacts is fully shown in the aforementioned patent to Shafer, No. 2,315,741 and in view of this disclosure reference may be had to this patent for further information. These contacts are in the brush magnet energizing circuit and together with the door contacts |63 are provided to insure that the brush .magnet is deenergized and the related brush is in down position when the door is open or when the carriage is manually back-spaced. These interlock contacts insure that the brushes IUI are in down position to prevent their injury by backspacing the card.

auxiliary keyboard The operation of the machine Will now be given mainly in connection with the wiring diagram of Figs. 7 and 8 and there will now be described the circuits which are operative for causing punching of a card and typing by the typewriter under control of the auxiliary keyboard K. As previously described, when the digit keys of the auxiliary keyboard are operated the individual contacts |24 (Fig. 7) will be closed as well as the bail contacts |23. Closure of contacts |24 will select duplicating or punch selector magnets 45 for energization. Current is supplied by the power supply lines |30, and |3| and `many of the circuit connections are completed through contacts |32 (Fig. '7) which are well known latch contacts in the card punching machine. When a key is depressed a circuit will be completed from the line |3I, through latch contacts |62 which are closed during key operations, wire |33, through punch bed contacts 42| Yand through the magazine contacts 4|8. VThese two last mentioned contacts correspond to the similarly designated contacts in Patent No. 2,285,289, and contacts 42| are shown in Fig. 4 as well. As long as there are cards in the supply magazine contacts 4|8 (Fig. 4) are closed and when a card is in position on the card carriage contacts 42| are closed. The circuit then extends from contacts 42| and 4|8 through normal transfer relayV contacts R55a, thence through bail contacts |23, through transfer contacts R35a, at normal, thence to a wire |34 which is connected tcone side of all the key operated contacts |24. The closure of said contacts |24 by. the operated key will then extend the circuit ,through the individual connecting wire |35 in a cable to the corresponding punch selectingmag'- net 45. The wiring connection from the other side of the duplicating or punch selecting magnets 45 is through the R|4 relay to theline |30 for punch selecting magnets |-9 inclusive, and for duplicating or punch selector magnets 0, and l2 the circuit is completed to line |3 through the R|3 relay. Punch selector magnets 45 will now shift the related interposer 5|) (Fig: 4) to select the desired punch 55 for operation.

The circuit to energize the punch magnet 66 to actually effect the punching operation is-from the line |3| through latchV contacts |2, punch magnet contacts 65, through relays R41 and R42, through normally closed contacts-R56d; wire |38, punch magnet 56, wire |39 to line |3. Punch magnet 66 then attracts its armature 61,- opening punch magnet'contacts 65 and deenergizing relays R4| and'Rfi.V A supplemental circuitV is provided to maintain punch magnet 66 energized for time determined by the closure of floating rearn contacts |2811. This circuit extends through either relay contacts R|3a or Rl4a, wire |31, floating cam contacts` IZBa, wire |36, latch contacts |32, to line |30.

When it is desired to e'iect typing concomitantly with card punching the typewriter operating solenoids 33 are energized.` In series with each punch selecting magnet 45 is a relay magnet |44 which is energized concurrently with the punch selecting magnet 45. Each relay |40 closes its respective contact lilla to extend the impulse circuit from the key contacts |24 relating to keys 0-9 to the typewriter solenoids 33. It will be noted that only 0, 1-9 relays |40 cause the energization of the corresponding typewriter solenoids 30. The circuit for the 1-9 type bar solenoids 3E; is completed through R|3b and R|4b contacts in parallel with each other, through the R46 relay, thence through relay contacts R551), relay contacts R38a, both of which are normally closed, thence to line |33. The energizing circuit for the 0 typewriter solenoid 'extends from the relay contacts |4a pertaining to the 0 relay |46, thence through relay contacts 52h now normal, to the 0 typewriter solenoid 30, and thence by a wire |4| to the relay contacts R551), through relay contacts RSSa, to the line |30.

A holding circuit is provided for the relays |40 which extends through the respective contact |401) to a line |42, thence through relay contacts R5'id, through the floating cam contacts |281), wire |35, latch contacts |32 back to line |30. Therefore, these relays are retained energized until the oating cam contacts |2819 open which is when the card carriage has skipped to the next column position. The circuit for the typewriter solenoids 3t, 1 to 9, inclusive, is opened whe relay contactsRlSb and R|4b open. Y

Multiple typing and single column punching at margin position of typewriter and card punch This is merely illustrative and by variations in plugging other typing can be effected.

The #t and are typed automatically and preferably by the following circuit arrangement:

In a manner disclosed in the aforementioned Doty patent, No. 2,318,299, theCR carriage return 1 and sign control vsolenoid is energized which returns the typewriter platen carriage to the left hand margin position and at such position insert contact 34 #l closes (see Fig. .8) and picks up R63 relay by an obvious circuit. This transfers contacts H6311. It will be noted 'in the circuit diagram that for illustrative purposes a `plug connection 143 (Figs. 7 `andi'S) is made from the #l column readout plug socket to a plug socket 144 connected to the center blade `of contacts REM and individual plug connections are made from |45, 146 plug sockets of the H6311 contacts to plug sockets connected to the period control relay R19 relay R23, respectively.

' `After punching operations Vfor a cardv are completed, the carriage isv returned by -circuits fully described in the last mentioned Doty patent and the punched card is ejected in the normal manner and, as is well known, latch contacts 102 close. VA circuit is now completed from line` 131 through latchcontacts 1102., wire 136, oating cam contacts 128a, com-mon contact bar 13, brush 12 at column 1 position to the contact point '14 of Acolumn l, associatedr plug socket '15, plug connection 143 to plug socket 14'4, through transferred contact 63d, plug connection 146 to the R23- relay, the circuit for R23 relay being completed through R32 relay, R630 contacts now closed to line 130. R23 relay closes the R23a contacts and a holding circuit for the R23H coil is effected through rsuch contacts through the normally closed punctuation common contacts 14'1 (Fig. Il.) to line 131. The R23 relay closes its R23b contacts and a circuit is completed -from line 131', to the normally closed type bar bail contacts 148, (Fig: 12') throug the normally closed space slide contacts 14'9, RSM` transfer relay contacts now normal, through R231# contacts, the it sign printing 'control solenoidl 30, to line 130. This will effect the operation of the# sign typewriter key and this will* Abe printed at the left hand margin of the sheet in the typewriter and the typewriter carriage moves inthe usual manner out. ofV the left hand! margin position and #l` insert' contact 34 Iopens to `drop out the R63 relay; Rad contactstransier to normal and the R63acontactsfopen1 The hold cir/cuit for theV hold coil `of `R23 relay, and in tact for the relays R19-25, is through the contacts `14'1. rIihe` manner in whichl these contacts` are opened, isbestshown inrFigs. 11 and l 113. Eachof thexpunctuation` typing keys for typing the is. operableby the -cam unit shown in Fi`g.f2f and' the. carrier 15 `hasa roller I55fwhich shifts a related slide 15B.- which has a cam projection 15T cooperating with a roller |58! carried by an arm |59 pivoted at 160. Now referring to Fig, 1'1", each arm; 159' is connected by a rod 161 and said' rod carries a member 162" for opening the' contacts 111'1.` Thus, the operation of each of thed'escribed punctuation keys opens the hold `circuit for the h'ol'd` coil of the' energized relay.

The punch carriage isat norm'alposition and although R631Z contacts (Fig) transfer to normal, no circuit connection is completed to. R19 relay at this' time because both R6'3a and R421; relay contacts are' open; The printing of' the it sign" is anindicati'onV tol the operator thatV the digit 5"is to'be now recorded on the sheet' in the typewriter and' punched onthe card and accordingly the: i155"` key of:v the auxiliary keyboard is operated andi by Vthe circuits previously described the-5 punch selecting magnet 45 andthe 5 typewriter" solenoid 3111 are energized; This will ef- -i'ecti concomitant; typing and punching ofr the 10 digit 5 on the sheetl in the typewriter and the card, respectively. In this operation of the punching machine the R42 relay is energized and the R421; contacts close (top of Fig. 8) and thus complete the circuit to the R19 relay which vis through the R631Z contacts now normal and plug connection 145. R19 relay closes its R191: relay contacts, eiecting a holding circuit for the RIBH winding through punctuation common contacts |47, as before. Relay R19 closes its R119b contacts to pick up the period solenoid 3D but the circuit is not completed at this time in order to provide a desired sequential operation between the 5 digit type bar and the period type bar to prevent any conilict. When the R41 relay is energized as a result of the digit card punching, as previously described, the R4Ia contacts (lower left of Fig. 8) close to complete a circuit from the line i311, wire |50, through the pickup winding of the R62 relay, R41a contacts, wire 151, latch contacts 102 to line 131. R62P coil (lower right, Fig. 8) transfers the R621; contacts which thus opens the energizing circuit for the period control solenoid 30. A hold circuit for the R62II relay (lower right, Fig. 8) which is picked up by transfer of R621; contacts is provided through Rt2-a contacts now transferred, the space cam slide contacts 149, type bar bail contacts 148, to line 131. VAfter typing 5v the type bar bail contacts 148 open, thus deenergizing` the RGZH coil and contacts R52a transfer back to normal. When the type bar bail contacts 148 close the energizing circuit is nowcompleted to the period control solenoid 3U and the period is typed after the digit 5.

The type bar bail contacts |48 are normally closed but open at each typing operation by means of the arrangement shown in Fig. l2. Plate 153 is the well known universal member provided for moving the ribbon in the well known Electromatic typewriter, and corresponds to element 31 of Patent No. 1 950,762.

summarizing, the above circuit arrangement provides for the typing of two signs by automatic key strokes and the intermediate digit by a vmanual operation. After punching the digit 5 the punch carriage escapes to the next column position and correspondingly the platen spaces to the next typing position on the sheet.

Slide-in cmd slide-out operations Herein the present machine provides for automatic typing or control functions which Vare set in operation by plugging connections from the column readout or" the'punch `and comprise operations which fall into two groups. `The rst group comprises so-called slide-in operations which are operations initiated as the brush of the readout moves into a column position. The second class of automatic operations are those which are not initiated immediately upon the brush of the readout sliding into av column position where a plug connection may have been made for that column but are to be initiated on moving out of a column position. In this group are the Voperations which are effected for typing punctuation or selective marks after digit typing. While the previous chapter described an automatic operation of this class, nevertheless the repeated description will be given.

Slide-out operations This group includes the solenoids R19 to R25 which, when energized, perform the function. designated by` such relays. If, for example, it is R641), the punctuation common contacts |41,

`desirable toprint a period, diagonal line, asterisk, etc. or even effect a spacing operation after a number has been typed in a column of the sheet, a plug wire is made from the column readout to the selected relay. If, for example, a period is to be typed afterga number is typed in column 10, a plug connection is made from column of the readout tothe plug socket of the period relayrRl 9 so that as the card carriage spaces from column 9 tocolumn 10 a circuit is completed to the period typing control relay RI9, in the assumed example. However, the energizing circuit of this relay is incomplete by reason of relay contacts R42@ which are, at the present time, open.

When the auxiliary keyboard is operated the desired digit will be typed and punched on the card and by circuits previously described relays R4| and R42 are picked up. R42a closes to energize the Rl 9 relay and its holding circuit is completed by the R|9a relay contacts and the punctuation common contacts |41. R|9b contacts will close to complete the circuit at this point to the period control solenoid 39 but the circuit will be open at R621; relay contacts which transferred as a result of the R62 relay having been picked up by the R4|a contacts. R52l-I coil is held through R62a relay contacts now transferred, the space cam s'ide contacts |49 now closed and the typewriter bail contacts |48. When the typewriter is operated to print the desired type, the type bar bail contacts |48 open (Fig. 12)` as previously described and R62I-I coil deenergizes and R62a contacts transfer back to normal. When the type bar bail contacts |48 close after typing the desired digit a circuit is .now completed through the R|9b contacts, the period control solenoid 30, R39 relay to the line |09. Thus, the energization of the period control solenoid will effect the operation of the typewriter key for causing the period to be recorded after the printed digit. When the punctuationY common contacts |41 open the hold circuit for the RIS relay will be broken.

In this same group are tabulating and carriage return operations controlled by relays R26 and R21 which obviously should be effected after recording of a digit. These control functionsl are delayed by reason of the opening of contacts R62a so that the energizing circuit for the solenoids 30 controlled'by the b contacts of such relays R26 and R21 cannot be completed until after the typing operation.

The holding circuit for the holding coil of R21 relay is through its R21a contacts, relay contacts back to the line |3|. The R21 relay closes its R21?) contacts to pick up the carriage return solenoid 30 which thus operates the carriage return key and the carriage vreturn mechanism of the typewriter returning the platen carriage to the left hand position. When this solenoid is energized the typewriter cam unit shifts a slide |56 (Fig. 9) and in the manner previously described causes the carriage return slide contacts |63 (Fig. 10) to close, thereby picking'up relay R64 by an obvious circuit in Fig. V8 and which relay holds Vthrough the R64a contacts, R63a contacts and the type bar bail contacts |48 back to line |5|. The carriage return slide contacts |63 are specially controlled and are controlled by a toggle so as to open at the end of the carriage return movement. This toggle comprises link '12 of the typewriter shown in Patent No. 2,200,767, and therefore, is well known. The deenergization of relay R64 at the end of the carriage returnA will open relay contacts R646 to break the holding circuit of the holding coil of R21 relay. Incidentally, theR64d contacts open the energizing circuit to the R60 and R6| relays through the respective insert contacts #2 and #3, 35 and 36, and thus prevent these relays from being picked up, although these insert contacts 35 and 36 may be closed during the return movement of the carriage.

With regard to the tabulating control relay, which is the R26 relay, it will be noted that its hold circuit for the R2 6H coil is through its R26a contacts and the tabulator slide contacts |65 back to line |30. ergized by the closure of the R261) contacts the cam unit operates a slide likeslide |56 (Fig. 9) but arranged to open contacts |65 which vbreak the holding circuit for the R26I-I coil. f` I In the delayed operation groupare operations controlled by R29, R30 and R3|,relays, which effect operations delayed by the opening of contacts R42a. The controls effected by such 'relays will be subsequently described in connection with master card control of duplicating operations described in the chapter headed Printing and Punching Data Represented by Master Card on Typewriter Sheet and Card, Respectively.

Slide-in operations In contrast to the operations just described the present machine has provisions for effecting other operations which are initiated immediately as the column readout spaces to the next column position. These relays are designated R49, R50, R5| and R52, (Fig. 8), it being evident that by selective plug connections from the column readout socket 15 to the desired one of such relays they are picked up immediately upon the spacing of the column readout to the next column position. In other words, if relay 49 is selected for energization as the column readout moves into the column from which a plug connection has been made, relay R49 will be picked up so that when punching is effected in the next'column, typing operations will be initiated under control ofthe auxiliary keyboard. On the other hand, if the R50 relay was picked up punching would not be effected for the column to which the col' umn readout spaces. Energization of the R5I relay will terminate typing operations for the column that the column readout moves into which corresponds to the plug socket of the column readout having the plug connection to the R5I relay.

.The circuit diagram there are corresponding relays in the patent to Doty, No. 2,318,299 in which complete information as to the manner in which the functions are performed may be found.

Zero suppression The R52 relay is a relay of the type in which Voperations are initiated immediately upon the i3 Referring to Fig. '1 (upper right hand), thel R526 contacts transfer so as to transfer impulses' which would. normally be drectedto the 0 typef When the TAB "solenoid vt0V is en-A does not include the var- `ious controls by relays R49, R50 and R5| since `writer solenoid30 topbe directed-'byrwire |61 to the space key solenoid |68, the circuit toV line |30 being completed through 55h and R38 relay contacts. Thus, instead of printing zeros inV the leftihand column positionsthe platen typewriter carriage is merely spaced, thus suppressing typing-'of zeros. The present machine has two space solenoids |68 (Fig. 7) and 30 (Fig. 8) to operate two different space levers in the typewriter keyboard. The automatic space solenoid 30 operatesa lever which is without a key top and acts directly upon the universal bar controlling the `type carriage bar escapement mechanism. The

`zero suppression can be terminated by typing a significant digit to pickup R40 relay (Fig. 7) to open contacts Rla, or'by-printing a period4 and picking up R39 relay and opening R39urelay contacts.

Means to epect multiple hole punching in each card column Afirstcolumnwhere multiple punching is to start, aplug connection is made fromthe desired plug socket 15` (Fig. 7) to the plug socketof the R51 relay, (Fig. 8) thus completing anenergizing circuit through normally closedRSSd relay contacts at -this `card column position of the carriage. A hold circuitforythe R51 relayis made through the R51u contacts, R580, contacts now closed, wires |66, back to line |3;|' through the latch contacts` |02. Also, through the R36() contactsA the energization circuit to theA space solenoid |10 is completed through wire |1'|, wire |39 (Fig; 7) to -line |30. Energizationof the multiple punch control solenoid |10f(see Fig. 15) operates the escapement mechanism so that the holding dog is held down to prevent escapement to the next column.

The punch space solenoid |13 moves a bell crank lever t` clockwise about its pivot stud 50|, thefpl-unger of the solenoid having a pin 532 engaging in a slet 5t'3zof the bell crank. A thrust bar-501 pivctedf atllf to the bell crank 500 rocks counterclockwisean arm .50? on the escapement idog control shaft A pin ivon a castingsecuredfon this: shaft: engages in a slot 5|0 ofthe escapement'dog 51| and rocks this dog into engagement withY theu rack bar 5| 2. At the same time agpin 5|3 'engaging `an elongated holeltof the second escapement dogli'l-S' lifts the latter out ofengagement with the rack bar and allows it to jump forward over the next tooth of Vtherack bar, under the force of spring 5K5. Therack bar is thus locked until the multiple` punch solenoid is deenergized However, when this solenoid imisdeenergized its release will enable the escapement mechanismto operate in the regular way to space to the next column. The transfer of the Rillb contacts (Fig. '7, upper left) transfers the-energizingicircuit from the space key IHS to the R36P`coil. R510?! contacts (Fig. 7) transfer to (thus transfer the duplicating relay hold circuit* through the R35a contactsand the latch contacts |023 back ltozlinevll'. `Thermachinephas now: been conditioned for 11 enabling multiple; card .punching in .a column.,y Thearstdigit key of the auxiliary key- .hoard is 1 depressed .and in the manner explained thepunchzimagnet.-Elwill .eiect the desired digit `Punching.

When R35 relay energizes for each digit key operation and` space key operation. the Rtolxcontacts (Fig. B) open to open the energizing circuit of the R51 relay but the latter, is still energized by its holding circuit. The second digit key depression of the auxiliary'keyboard is now made by the operator :andra repetition of the above operations occur. AfterA multiple punching in a card column the space keyof theauxiliary keyboard is operated andrecallingthatthe Rlh contacts (Fig. '7, upper left) are now'transferred, depression of the spacekey IHS will complete a circuit from line |31 through latch contacts |02, punch bed contacts 42|, Vmagazine contacts 41B, R55@ contacts, auxiliary space: key contacts |2451, R35?) contants, :space key contacts |2482, through R511? contacts (Fig. "1, upper left) now transferred to R35?, coil `to line 30.. The hold circuit for the RBEH coil is effected through the R36u contacts, the-space key contacts |2llS2', R351? contacts, auxiliary keyboard space contacts |'24S|, REaf, contacts,` magazine contacts M8, punch bed contacts 421|, latch contacts |92; to line |3|.

PrintingA and punching data represented by master card 0n. typewriter sheet and card, respectively It.A isfrequently desirable to reproduce on the sheet in the typewriter and also upon theY blank card :in the punch data represented bythe master oardfwhich', it is` recalled, is analyzed by the master cardanalyzinglmeans comprising brushes i the latter is picked up at 15 print this data a plug connection is also made from plug socket No. 29 to a plug socket |11 (Fig. 8) designated Start print duplicate to thereby energize the R3 IP relay coil after the RMP relay coil has been energized. The Start print duplicate `control is the delayed operation type since R3IP relay is in series circuit with Ra contacts and further in the present machine a Start print duplicate operation is initiated after a tabulation or any movement effected by typing, tabulating, spacing, carriage return, etc. to a position to close Insert #2 contacts 35. Therefore, a plug connection is made from the plug socket 'I5 of column No. 29 to the TAB plug socket to pick up the R28 and R31 relays. The R25 and R31 relays are energized when the column readout slides into column 3-0 position and R26 relay is held through its respective R25a contacts and the TAB slide contacts |55 as previ- .ously described.

R513 relay (Fig. 8) when column 30 position, it will close its respective contacts R54a (Fig. 8) thereby closing the energizing circuit for the R54H relay through the R55@ contacts and'R29a contacts now closed. At the same time, the R55H coil in multiple with the RMR is energized. Both of these relay coils are maintained energized until the termination of the punching duplicating operations when R29 relay coil (Fig. 8) is picked up to open the respective R29a contacts. R55?) contacts (Fig. 7, right center) open to break the return circuit of the typewriter solenoids. Rtb contacts (below R555) close to complete a circuit to energize the brush magnet I 04 from the line |3|) through brush magnet .Considering now the |04; column cutout contact H5, door contact |99, R551; contacts, wire |38, latch contacts |92, tc line |3|. Energization of the brush magnet |04 (Fig. 5) will lift the master card analyzing brushes I9| in contact with the contact roll |95.

Concurrently the R'd contacts (lower left, Fig. '7), close to complete the circuit to the contact roll |95. The R55@ contacts (Fig. 7, lower left) are transferred to open the energizing circuit under control of the auxiliary keyboard contacts |24 to prevent misoperations in the event the auxiliary keyboard is operated during duplicating operations. The transfer of such contacts R55a completes a circuit from line |3| to latch contact B52, wire |33, punch bed contacts 42|, the magazine contacts M8, R55a contacts now transferred, R38 relay, wire |13 to line |3|) to energize R38. R38 opens R38a contacts (Fig. 7, right center) to open the return circuit for the typewriter solenoids even though R560 contacts, which are in shunt with R551) and R38a, are closed, as will be presently described. Y

Referring now to Fig. 8, R54 relay closes' the R54c contacts to complete a circuit from the line |30 through R3IH and R561? in multiple with each other, through R3Ia relay contacts now close-d as a result of the energization of R3IP coil, R540 contacts, R69@ contacts now closed, thence back to the line |3| through latch contacts |02. Contacts R540 also maintain a hold circuit for RS'll-I through Rla and R54c. R561? closes R55a contacts to pick up R55H through R53a., Ra, R5lla, R29a. R55 closes R560 (Fig. 7, right center) to close the return circuit of the typewriter solenoids. RSI relay opens R3|b contacts and R31 opens its respective contacts R311) (see Fig. 7, lower left) to thereby break, at two points, the energizing circuit leading to theV contact `rol1 |05. This opens the master card analyzing circuit even though R54d contacts have closed and the R56 relay coil has closed the R59c contacts which are in the return circuit of the typewriter key solenoids. lThus, the master card analyzing means is ineffective until both contacts R3`|b and R3 lb close which is effected when the tabulation of the typewriter carriage has been terminated.

When the tabulating relay R25 has been picked up it closes its contacts Rito to energize the tabulating control solenoid 3|) of the typewriter and the typewriter escapes in a customary manner until a predetermined position of the typ-ewriter carriage is reached, determined by the position of the well known tabulating stop. At this position #2 Insert contacts 35 close to thereby complete a circuit previously described to the R55 relay. R59 relay opens the Rlla contacts and drops out the RSIH relay coil, R3'II-I relay coil and R5GP relay coil.

Deenergization of the R3I relay now permits R3Ib (Fig. 7) contacts to close the energizing circuit to the contact roll |55. Also, since the hold circuit for the RB'IH relay is opened, R315 contacts close to complete, at this time, the circuit to the contact roll |55. Therefore, the first column of the pattern card associated with the analyzing brushes II will be analyzed and the respective punch magnet and typewriter solenoid will be picked up to concurrently punch and print the same digit. When the column readout moves out of this first column position Ri relay drops out andV its contacts R3Ia (Fig. 8) open to maintain RSIH and RESP deenergized. However, the R56I-I relay coil is maintained energized through the R5I5a, R3a, R'ila contacts, R29a. contacts to line |3|. Thus, R56c contacts (Fig. 7) will be maintained closed to complete the return circuit of the typewriter solenoids 30.

Card punching operations under control of the master card are carried out as in the aforementioned patent to Lee and Daly, No. 1,976,618, and as a result of the energization of a punch selecting magnet 45, the interposer will be shifted to close punch contacts 65 and a. circuit will be completed from line |3|, through latch contacts |52, punch contacts 55 but since contacts R56d are now open a circuit is completed to the R46P coil (Fig. 8) to line |39, the impulse being transmitted to such coil in view of the presently open contacts R5Ed, which contacts are maintained open during card punch duplicating operations. The RGEP coil closes the Rda contacts (Fig. 7) and thus a delayed impulse is transmitted to the punch magnet B5 and also to R42 and RAI relays. This delay in punching operations is effected because the operation of the punch concurrently with printing must be slower than with punching alone.

When the column is reached where printing and punching duplicating operations are to be terminated, a plug connection is made from the respective column. For example, if the last. duplicating operation is to be eiected in the blank card in column 4I] double plugging therefrom to plug sockets |18, |19 designated Stop duplicating and Stop print duplicating will energize the R29 and R39 relays after the R42a contacts close. R29 relay opens the R29a contacts (Fig. 8) and drops out R54H and R55H relays. R350. relay contacts open to drop out R56H and the machine is now in a Vcondition it was just prior to start printing and punching duplicating operacomitantV digit typing and digit punching are completed.
